Brian those graphs were the BC results from using 10.3gn JSB heavies, I think 12 ft/lb occurs at about 725 fps with those?
I would be interested to see the same test done with 8.44's. I have no doubt Harry will do that too.
I have a graph which I think Harry created with the BC results at different velocities for some of the .22 JSB pellet weights, like those .177 heavies they all seemed to be at their best at velocities a little over what we can run here.
HFT, for people with only 2 buttucks!
